hey guys im the new guy here looking for a recommendation. I been stuck on trying to make my mind up for the past 4 days. I like the ath-m50 because of the price and they are highly suggested and the beat pro's ( i can find them for $200), as for iem i like the sony eb90ex. I really dont want an amp but if i have to get one it would be a fiio e11 or e6

1. I listen to rap and r&b
2. they will be powered by my galaxy note 2
3. i would like the to be portable
